Snowfall total map for the April 14-16 winter storm
Unbelievable how much snow has fallen the past 3 days, and the extent of the heavy snowfall of over 6 inches is impressive for mid April!
Radar loop from Friday, April 13 through Sunday, April 15, 2018
Incredibly cold April so over much of the U.S. with the greatest departures from average covering the northern Rockies, northern Plains and upper Midwest. Warmer than average spots, southwest U.S. and central/southern Florida.
Powerful storm is still spinning away as it slowly pulls away from the Great Lakes, it’ll take another 12 hours or so before it finally moves away from the Great Lakes.
It’s been an active last few days not only in the snow department, but also with severe weather. The map below shows all the severe thunderstorm and tornado warnings that were issued by the National Weather Service over the past few days. Even had the first severe thunderstorms this spring in parts of southern Minnesota, southern Wisconsin and southeast South Dakota this past Friday.
Winter Storm Watch for late Tuesday night through Wednesday night for far southern Minnesota, northern Iowa (Blue area on map)

Northwest flow aloft covered the upper Midwest today behind this past weekend’s powerful winter storm. Mostly cloudy skies over most of the area today but there has been some partial clearing during the afternoon which allowed for some peeks of sun. Highs today still no-where close to where they should be for mid April with highs in the upper 20s to middle 30s (Should be around 50 degrees on April 16)
Partly to mostly cloudy skies for tonight with some snow showers and flurries in extreme northeast Minnesota and over in Iron County in northwest Wisconsin where some lake effect snow will persist tonight. Lows will be in the teens and 20s but a few spots could dip into the single digits if skies clear enough.
Should have more sun for Tuesday compared to what we saw on Monday. Highs in the mid 30s to low 40s.
Our next system to keep an eye on looks like it will stay far enough south to bring any significant amount of snow to northeast Minnesota and northwest Wisconsin but there could be some flurries or snow showers impacting parts of the area on Wednesday but little or no accumulation is expected the way it looks now. Easterly wind returns for Wednesday but shouldn’t be nearly as strong as it was this past weekend.
Note: The good news is that it finally looks like will have an extended period with at least average temperatures starting late this week which should carry over into next week per long range model trends. Daytime highs near 50 or into the 50s are expected over most of the Northland, could even climb into the 60s, which if that happens would actually be above average for a change!
Forecast for Duluth and Superior
.Tonight… Partly to mostly cloudy. Breezy. Low 19 to 24. Wind north to northwest at 10 to 20 mph with gusts to 25 mph.
